Because it cannot be falsified.
I just showed you several ways in which it could be falsified and there are lots more.
It is largely based on “models” but the models themselves are deficient.
It is NOT largely based on models and GCMs are not deficient.
I assume you know this. Check this out from 2008:
Tim Ball is a very poor source. Almost everything he says here is demonstrably false.
Can you honestly point to anything that validates these models?
I have already done so, repeatedly, but if you'd like to see it once again...
I said no such thing and suggested no such thing and implied no such thing. See a pattern there?
We said:
My apologies if I've misinterpreted what you've said here, but you seem to be saying that you do not accept that the greenhouse effect is a global effect. The only other alternative I know of is that it be regional. If you meant something else, please explain.
No links. No evidence. No offers of any proof.*
* - that CO2 was responsible for 1/3rd of pre-industrial greenhouse warming and is now responsible for 1/2.
That is because I have posted it several times before.
Why carbon dioxide matters
Carbon dioxide is Earth’s most important
greenhouse gas: a gas that absorbs and radiates heat. Unlike oxygen or nitrogen (which make up most of our atmosphere), greenhouse gases absorb heat radiating from the Earth’s surface and re-release it in all directions—including back toward Earth’s surface. Without carbon dioxide, Earth’s natural greenhouse effect would be too weak to keep the average global surface temperature above freezing. By adding more carbon dioxide to the atmosphere, people are supercharging the natural greenhouse effect, causing global temperature to rise.
According to observations by the NOAA Global Monitoring Lab, in 2021 carbon dioxide alone was responsible for about two-thirds of the total heating influence of all human-produced greenhouse gases.
In the past 60 years, carbon dioxide in the atmosphere has increased 100 times faster than it did during the end of the last ice age.

By increasing the concentration of greenhouse gases in the atmosphere, we’re amplifying the planet’s natural greenhouse effect and turning up the dial on global warming.

From 1990 to 2019, the total warming effect from greenhouse gases added by humans to the Earth’s atmosphere increased by 45 percent. The warming effect associated with carbon dioxide alone increased by 36 percent.

According to current scientific understanding, carbon dioxide
(CO2) is responsible for roughly two-thirds of the total heating influence from human-produced greenhouse gases, meaning it contributes significantly to Earth's greenhouse warming; with estimates placing its contribution around 60-70%of the total human-caused warming.
Key points about CO2 and greenhouse warming:
- Dominant greenhouse gas:
CO2 is considered the primary anthropogenic (human-caused) greenhouse gas, contributing the most to global warming.
- Long atmospheric lifetime:
CO2 remains in the atmosphere for long periods, allowing its warming effects to accumulate over time.
- Impact on temperature:
Increasing CO2 concentrations directly correlate with rising global temperatures.
